Hello everyone! this post describes how we are going about determining the size cut-off of the membranes we make through nanosphere lithography. These are 120 nm thick silicon nitride membranes with controlled pore size between 320 and 80 nm. A…

As part of my thesis (and a tie-in to the microplastics research our lab has been conducting) I’ve been working on creating a measure of membrane capacity. A robust way to do this involves using microporous chips and polystyrene beads.…

This post is dedicated to our ongoing collaboration with Dr. Marchi at Centre national de la recherche scientifique (CNRS) in France. The basic concept of the project is simple (Fig.1) and involves attaching a microporous membrane on top a 3D…

As part of Aim 1 of my PhD, I am looking into mechanical characterization of ultrathin membranes to explore the effects of porosity on the structural integrity and determine how porous we can go with a porous membrane, and last…

Last time this project was discussed at NRG, Henry was the project lead (we miss you, Henry). He was observing bladder epithelial cell (BdEC) invasion and migration in co-culture with T24 bladder cancer cells. Here are links to his previous…

Hi All, This post is more of a dump of figures that I have put together for Dan’s and my upcoming Journal of Membrane Science manuscript. I have included figures and captions, so any feedback would be greatly appreciated.

Introduction Etaluma is a company that builds high resolution microscopes in a compact format for integration into cell culture incubators. This shifts from the traditional stage top or incubator cage approach to live cell imaging to allow for steady time-lapse…

Introduction Currently, no FDA approved drug exist for the treatment of sepsis. Past sepsis pharmaceuticals attempted to target mediators of the innate immune response. These drugs, however, struggled to balance remedial immune suppression from complete immune knockdown in a patient…

This initial aim of this project was to obtain “pockets” with sub-100nm pores, while the top opening is much larger. Dr. Carter is the mastermind behind this project. The following simple fabrication process diagram explains the current approach. After initial…

Thanks to Ian Krout for the data. As covered in our last post, we hope to distinguish between different kinds of microdebris caught on silicon nanomembranes through the material’s different melting points. Plastics can have a wide range of melting…
